CrowTrends

CrowTrends is a web app used to find out what the internet says about your favorite stocks. It compiles, analyzes, and helps you visualize the online conversation around the top equities and ETFs. The site works as a dashboard that can be used to see trends of sentiment, volume, and the price of a particular stock.

I built and designed the front-end portion of the site from the ground up by creating a custom-made design system. CrowTrends is mobile optimized, accessible, and features an intuitive and elegant design with user experience at its core.
